Struct gtk4::FontDialog
source · #[repr(transparent)]pub struct FontDialog { /* private fields */ }
v4_10
only.Expand description
A FontDialog
object collects the arguments that
are needed to present a font chooser dialog to the
user, such as a title for the dialog and whether it
should be modal.
The dialog is shown with the choose_font()
function or its variants. This API follows the GIO async pattern,
and the result can be obtained by calling the corresponding
finish function, such as Gtk::FontDialog::choose_font_finish()
.
See FontDialogButton
for a convenient control
that uses FontDialog
and presents the results.
Properties
filter
Sets a filter to restrict what fonts are shown in the font chooser dialog.
Readable | Writeable
font-map
Sets a custom font map to select fonts from.
A custom font map can be used to present application-specific fonts instead of or in addition to the normal system fonts.
Readable | Writeable
language
The language for which the font features are selected.
Readable | Writeable
modal
Whether the font chooser dialog is modal.
Readable | Writeable
title
A title that may be shown on the font chooser
dialog that is presented by FontDialog::choose_font()
.

Implementations§
source§impl FontDialog
impl FontDialog
sourcepub fn new() -> FontDialog
pub fn new() -> FontDialog
sourcepub fn builder() -> FontDialogBuilder
pub fn builder() -> FontDialogBuilder
Creates a new builder-pattern struct instance to construct FontDialog
objects.
This method returns an instance of FontDialogBuilder
which can be used to create FontDialog
objects.
sourcepub fn choose_face<P: FnOnce(Result<FontFace, Error>) + 'static>(
&self,
parent: Option<&impl IsA<Window>>,
initial_value: Option<&impl IsA<FontFace>>,
cancellable: Option<&impl IsA<Cancellable>>,

)
pub fn choose_face<P: FnOnce(Result<FontFace, Error>) + 'static>( &self, parent: Option<&impl IsA<Window>>, initial_value: Option<&impl IsA<FontFace>>, cancellable: Option<&impl IsA<Cancellable>>, callback: P )
This function initiates a font selection operation by presenting a dialog to the user for selecting a font face (i.e. a font family and style, but not a specific font size).
The @callback will be called when the dialog is dismissed.
It should call Gtk::FontDialog::choose_face_finish()
to obtain the result.

pub fn choose_family<P: FnOnce(Result<FontFamily, Error>) + 'static>( &self, parent: Option<&impl IsA<Window>>, initial_value: Option<&impl IsA<FontFamily>>, cancellable: Option<&impl IsA<Cancellable>>, callback: P )
This function initiates a font selection operation by presenting a dialog to the user for selecting a font family.
The @callback will be called when the dialog is dismissed.
It should call Gtk::FontDialog::choose_family_finish()
to obtain the result.

pub fn choose_font<P: FnOnce(Result<FontDescription, Error>) + 'static>( &self, parent: Option<&impl IsA<Window>>, initial_value: Option<&FontDescription>, cancellable: Option<&impl IsA<Cancellable>>, callback: P )
This function initiates a font selection operation by presenting a dialog to the user for selecting a font.
The @callback will be called when the dialog is dismissed.
It should call Gtk::FontDialog::choose_font_finish()
to obtain the result.
If you want to let the user select font features as well,
use choose_font_and_features()
instead.

Returns the fontmap from which fonts are selected,
or NULL
for the default fontmap.

the fontmap
sourcepub fn is_modal(&self) -> bool
pub fn is_modal(&self) -> bool
Returns whether the font chooser dialog blocks interaction with the parent window while it is presented.
Returns

sourcepub fn set_filter(&self, filter: Option<&impl IsA<Filter>>)
pub fn set_filter(&self, filter: Option<&impl IsA<Filter>>)
Adds a filter that decides which fonts to display in the font chooser dialog.
